Review ArticleOpen accessIn the abstractImmunology of Septic Shock and Traumatic Injury: A ReviewWilliam Heuser, Marianne Frieri, Krishan Kumar, Anthony BoutinSepsis remains a major worldwide cause of morbidity and mortality and remains amongst the leading causes of death in medical Intensive Care Units (ICUs). Increasing injury severity associated with trauma is a significant independent risk factor for sepsis and many of these patients require intensive care unit resource utilization with increased rates of mortality. There are many postulated theories regarding … …American Journal of Immunology, Vol. 11, Issue 4 · 31 Dec 2015 · 7,003 accessesView PDFCite
EditorialOpen accessIn the abstractAre we Able to Harness the Immunomodulatory Power of Cytokines for Novel Autoimmune Disease Treatments?Giuseppe Nocentini, Graziella Migliorati, Carlo RiccardiSince the end of the 1970s, interleukin 2 (IL-2) has been known as a key player in T cell expansion/activation (Watson et al., 1980). In the late 1980s, some groups used IL-2 to stimulate the immune systems of tumour patients (Jacobs et al., 1986). The idea seemed brilliant and several attempts were made, but the results were disappointing (Lim et … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 2 · 22 Oct 2015 · 7,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Unilateral Cervical Vagotomy on Murine Dendritic CellsDaniel Sanzio Gimenes da Cruz, Ana Paula Nascimento de Lima, Patrícia Benites Gonçalves da Silva et al.The cholinergic anti-inflammatory pathway has been demonstrated to be an important mechanism that modulates several inflammatory diseases. This modulation occurs upon activation of the vagus nerve, which modulates splenic macrophages and lymphocytes through the predominant neurotransmitter, Acetylcholine (ACh). We hypothesized that this modulation could also take place in dendritic cells, as these cells represent a link between the innate and … …American Journal of Immunology, Vol. 11, Issue 2 · 12 Jul 2015 · 6,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractSerological and Molecular Investigation of Cutaneous Leishmaniasis in Healthy Individuals from an American Cutaneous Leishmaniasis-Endemic RegionRejane Cristina Ribas-Silva, Taisa Rocha Navasconi, Laís de Souza Braga et al.American Cutaneous Leishmaniasis (ACL) is a major, clinically relevant zoonosis in Brazil. The disease spectrum includes single, localized, cutaneous ulcers, diffuse cutaneous leishmaniasis and mucosal disease. A subclinical form of the disease has also been described in individuals living in ACL-endemic regions. The goal of this study was to employ immunological and molecular diagnostic methods to evaluate the presence of … …American Journal of Infectious Diseases, Vol. 11, Issue 1 · 23 Jun 2015 · 7,324 accessesView PDFCite
EditorialOpen accessIn the abstractNeutrophil Extracellular Traps as Therapeutic Targets for Inflammatory DiseaseRory R. KoenenNeutrophilic granulocytes, or neutrophils are the most abundant circulating white blood cell and constitute a first line of defense against pathogens. They are characterized by a large polymorphic lobular nucleus and the presence of many secretory granules in their cytoplasm. Neutrophils are essential for a functional host defense, as is evidenced by the occurrence of severe infections in individuals with … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 4 · 25 Feb 2015 · 8,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunological Processes in Cancer: A Link Between Inflammation and ImmunityVanessa Jacob Victorino, Isabela Casagrande Jeremias, Anne Karine Martins AssunçãoCancer is a worldwide issue and one of the most relevant death causes in child and adults. There are several causes that can lead to cancer development. It is well known that inflammation is one known hallmark of cancer and it favors tumor cells growth. Several alterations in immunological and inflammatory processes are caused in response to tumor presence and … …American Journal of Immunology, Vol. 10, Issue 4 · 17 Jan 2015 · 7,073 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Hypoxia-Inducible Factor-1α Signaling Pathway and its Relation to Cancer and ImmunologyBruno R.B. Pires, Andre L. Mencalha, Gerson M. Ferreira et al.Hypoxia-Inducible Factor 1 (HIF-1) is a transcription factor that is present in all metazoans from early embryonic development throughout adult life. It plays a major roles in the different stress responses that are triggered by low Oxygen (O2) levels and its expression is associated with cell survival. HIF-1 is a heterodimer protein that comprises the subunits HIF-1α and HIF-1β. The … …American Journal of Immunology, Vol. 10, Issue 4 · 17 Jan 2015 · 8,482 accessesView PDFCite
EditorialOpen accessIn the abstractGLUTATHIONE: A POSSIBLE LINK TO AUTOPHAGY IN SYSTEMIC LUPUS ERYTHEMATOSUSDilip Shah, Swapan K. NathIncreased free radical formation and altered redox state are of fundamental importance in the pathogenesis of autoimmune diseases including Systemic Lupus Erythematos (SLE). Free radicals are mainly derived from oxygen (Reactive Oxygen Species/ROS) and nitrogen (Reactive Nitrogen Species/RNS) at mitochondria, cellular membranes and the endoplasmic reticulum membrane as physiological responses to a variety of internal and external stress (Shah et … …American Journal of Immunology, Vol. 10, Issue 3 · 3 Sep 2014 · 12,773 accessesView PDFCite

Research ArticleOpen accessIn the abstractActin Cytoskeleton and Related Proteins Role During Immune Cells Migration, Polarity and Activation: An OverviewClaudio Vieira da SilvaImmune cells migration, polarity and activation are essential during host immune response. Upon recognition of specific peptides presented by Human Leukocyte Antigen (HLA) molecules on Antigen Presenting Cells (APC), lymphocytes execute subset-related functions such as killing, help and regulation. These cells travel through the organism in a succession of steps, including entry into tissues, interstitial migration, APC scanning, synapse formation … …American Journal of Immunology, Vol. 9, Issue 4 · 19 Nov 2013 · 6,780 accessesView PDFCite
